COMPOSITION GUTTER.

Specification of Letters Patent.

Patented Aug. 12, 1919.

To all whom t may concern.'

Be it known that I, Oris W. ANDERSON, a citizen of the United States ofAmerica, and a resident of Waterloo, Blackhawk county, Iowa, haveinvented certain new and useful Improvements in Composition Gutters, ofwhich the following is a specification.

My invention relates to improvements in composition gutters, and theobject of my improvement is to construct a gutter for carrying away thedischarges from eaves, the gutter being formed from layers ofwaterproofed material containing a rigid reinforcing body to maintain itin its troughed shape.

This object I have accomplished by the means which are hereinafterdescribed and claimed, and which are illustrated in the accompanyingdrawings, in which Figure 1 is a cross section of my improvedcomposition gutter as supported below the eaves of a building; Fig. 2 isa fragmental elevation of the abutting end parts of two sections of saidgutter, with the end parts of the waterproofing material removed toexpose the overlapped extremities of the intersticed reinforcements; andFig. 3 is an enlarged longitudinal section of like abutted and connectedend parts of two sections with the joint thereof secured and sealed bywaterproofing cementing material.

Similar numerals and characters of reference denote corresponding partsthroughout the several views.

In Fig. 1, B denotes a fragmental cross section of a portion of abuilding including its overhanging eaves, and A denotes my improvedcomposition gutter as supported pendently on the eaves and positionedbelow? the eaves to receive discharges therefrom.

The gutter A is trough shaped and may be of any desired form of crosssection, and may be suspended or supported'to receive from said eaves inany desired manner, or by any convenient means. I have shown the guttersupported on or under the eaves by wire hangers 7, each hangerconsisting of a single wire rod carried conformably around the gutter Awith its members bent toward each other across the top of the gutter andtwisted together at 8, the twisted parts being then fastened upon theeaves by nails 9.

The composition materials of the gutter may be varied in substance andrelative arrangement, the essential features being the combination witha trough of flexible waterproofed material of suitable reinforcing meansfor stiffening same and maintaining it in its desired shape. Thepreferred embodiment of my invention consists in placing a sheet ofintersticed metal or wire netting 1 between layers of flexible fibrousmaterial 3, such as paper felt. These assembled parts or sheets arepassed through a bath of waterproofing substance such as a melted orliquefied bituminous body. This waterproofing substance both lls theinterstices of the netting 1 and also cements the fibrous layers 3thereupon, while eXteriorly coating and waterproong said layers at 4.The combined sheets may then be shaped into troughs A which areafterward cut into sections of suitable length.

Abutting ends of such sections may be firmly connected and sealedtogether as shown in said Fig. 3. This is done by removing the layers 3from the abutting end parts of the netting 1 and overlapping the exposedend parts of the netting, a plurality of clips 6 being employed tofasten together said overlapped parts. The joint between the sections isthen filled in flush with the waterproof bituminous sealing material 5,which insures a non-leaking joint and a smooth continuous waterproofedsurface to the gutter.

A glitter of this reinforced composition will resist deformation andwill withstand the action of the elements for an indefinite length oftime.

I-Iaving described my invention, what I claim as new, and desire tosecure by Let- Y ters Patent, is:

1. A conduit formed of layers of brous material, an intermediate layerof foraminated material, and a waterproof adhesive filling substancebetween and cementing the fibrous layers to said intermediate layer.

2. A conduit formed of two alined sections'7 each section constructed oflayers of and waterproof filling material sealed over, fibrous materialwith an interposed layer of permeating and closing the joint betweenoraminated material which projects therethe sections.
